Forgive appearances: Super Mariscos looks dated and plays melodic pan pipes on the stereo, but it serves very good ceviche (seafood marinated in lemon or lime juice, garlic and seasonings), rice dishes and seafood galore, plus pasta and a few beef dishes. You can order most items in a small or large size, depending on your appetite.
Find it on a bend in the road in Sarchí Sur, 1km southeast of the plaza.
